During the 2020 presidential campaign, candidate Joe Biden railed against then-President Donald Trump's efforts to build a wall along America's southern border.

Yet in a startling reversal, President Biden recently caved to pressure from the ongoing migrant crisis and began building a wall of his own. 

DHS secretary: There is "an acute and immediate need to construct physical barriers"

USA Today reported that 26 federal laws, including those pertaining to environmental protection, are being waived in order to speed up barrier construction.

According to Reuters, the White House announced on Thursday that it would use funds allocated during Trump's time in office to construct additional wall sections.

Reuters noted that Department of Homeland Security (DHS) Secretary Alejandro Mayorkas released a statement in which he insisted that there is "no new Administration policy with respect to border walls" as the funds in question were set aside in 2019.

Nevertheless, Mayorkas claimed in a Federal Registry notice that "[t]here is presently an acute and immediate need to construct physical barriers and roads in the vicinity of the border of the United States in order to prevent unlawful entries into the United States."

Meanwhile, Fox News recalled how in 2020 Biden told NPR journalist Lulu Garcia-Navarro, "There will not be another foot of wall constructed on my administration."

Critics accuse White House of hypocrisy

The administration's about-face led to widespread mockery on the platform formerly known as Twitter as conservatives juxtaposed it with Biden's prior opposition to border walls.

Critics included the conservative comedy duo The Hodge Twins. They said in an X post, "Where isn’t the left accusing the Biden admin of racism and fascism for wanting a border wall?"

Kamala Harris once called border wall a "medieval vanity project"

Biden was not alone in having once slammed former President Trump's effort at constructing a physical barrier, as Vice President Kamala Harris did as well.

While running for the Democratic Party's nomination in 2019, Harris called the wall a "medieval vanity project" that "has never been about keeping the American people safe."

Congress did not appropriate these funds for Trump's medieval vanity project. Let's be clear: Trump's wall has never been about keeping the American people safe. https://t.co/tlZ9GRp7Wd
